Incorrect (dummy) Tax Jurisdiction Code in a/cing doc from SD

Hi Experts

We are using SABRIX (external tax system). Dummy tax jurisdiction code is maintained in OBCL which is picked in the accounting document interfaced from SD in case of export transaction involving US as origin country & CA as destination country. Tax jurisdiction code of the Ship to partner is CAON which is updated correctly in the billing invoice but the accounting document has the dummy jurisdiction code maintained in OBCL. I have checked all the related SAP Notes which are older than our current patch level.

Anybody who had a similar issue with resolution can kindly contribute their inputs.

Thanks in Advance

Best Regards
